OIL-BURNER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Applicationfiled February 24, 1914. Serial No. 820,531.

To all whom it may concern Be it known that 1, DAVID B. PATE, a citizen of the United States, residing at Hornbeck, in the parish of Vernon and State of Louisiana, have invented a new and useful Oil-Burner, of which the following is a specification.

The invention relates to improvements in oil burners.

The object of the invention is to improve the construction of oil burners, and to provide a simple, efiicient and inexpensive device adapted to be used in stoves, furnaces, etc, and designed for consuming crude petroleum and other hydro-carbon fuels and capable of completely vaporizing such material and of thoroughly mixing air with the oil vapor to secure perfect combustion and eliminate smoke and soot.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advan tages of the invention.

Fig. 3 is a transverse sectional view on the line 8-3 of Fig. 2. Fig. 4 is an enlarged detail sectional view of the vapor discharge nozzle. Fig. 5 is a side elevation of an oil burner illustrating another embodiment of the invention. Fig. 6 is alongitudinal sectional view of the same. Fig. 7 is a transverse sectional view on the the line 7-7 of Fig. 6. Fig. 8 is a side elevation of anoil burner showing another form of the invention. Fig. 9 is a plan'view of the same. Fig. 10 is a detail horizontal sectional view illustrating the construction of the guide for the adjustable generator. Fig. 11 is a vertical sectional view on the line 1111 of Fig. 8.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings, in which is illustrated the preferred embodiment of zontal mixing receptacle or burner proper 1 and a superimposed generator 2, which, in the form of the invention illustrated 1n Figs. 1 to 41 inclusive of the drawings, is

constructed of suitable piping and consists of upper and lower horizontally disposed arms connected at one end by suitable coupllngs 3 and a short piece or nipple 1. The upper arm of the generator is connected at the other end with a suitable fuel supply plpe 5, the flow of oil or other fuel to the generator being controlled by a valve 6. The fuel pipe 5 extends upwardly from the adjacent end of the upper arm of the gener ator, but it may be arranged in any other suitable manner, and the valve 6, which is preferably located at the lower end of the ipe 5, may be of any preferred construction. The lower arm of the generator 2 is supported by a central vertical leg or standard 7, preferably consisting of a pipe or tube, provided at the top with a T-coupling 8, through which the lower arm of the generator passes. The lower end 9 of the leg or standard 7 is threaded and screws into a threaded socket 10 formed integral with the receptacle 1 and arranged at the center of the top thereof. The coupling 8 may be smooth to slidably receive the lower arm of the generator, or it may be interiorly threaded and constitute a portion of the generator, the lower arm then consisting of two separate pieces of pipe.

The mixing receptacle or burner proper is preferably cylindrical, but it may be of any other preferred form, and it is provided with end walls. 11 and 12, the end wall 11 being imperforate, and the other end wall having a threaded opening for the reception of a tubular portion 13 of an air and vapor inlet. The air and vapor inlet, which has flared or funnel shaped outer portion 14, is adjustable through its threaded connection with the mixing receptacle or burner proper 1, andis adapted to be screwed inwardly and outwardly to. arrange the funnel or flaring portion 14 the desired distance from a vapor discharge nozzle 15 of a depending branch or arm 16 of the generator. The branch or arm 16, which. is tubular, extends down-' wardly from one end of the lower arm of'the generator, and it is provided at its lower end with an elbow coupling 17, into which is V 1 secured an exteriortubular body portion 18 of the vapor discharge nozzle15.

V The vapor discharge nozzle, which is horizontally disposed, consists of an exter orly threaded tubular body portion 13 and an interiorly threaded cap arranged on the outer end of the said body portion 18 and pro- I vided with a central jet aperture or perforation 19, through which the oil vapor from the generator is discharged into the funnel or flared portion 14 of the air and vapor inlet. The relative adjustment of the air and vapor inlet and the nozzle 15 of the 'generf ator enables the said nozzle to be arranged the proper distance from the air and vapor inlet to draw or-suck into the mixing receptacle the desiredamount of'alr to secure aperfect combustion of the vaporized fuel which is discharged from the mixing receptacle or burner proper through jet apertures 20. The said relative adjustment of the air and vapor inlet and the nozzle of the generator enables the burner to be used at different elevations, the distance between the" discharge nozzle and the air and vapor lnlet being increased in accordance with the increase in elevation, to cause the proper,

amount of air to mix with the vapor.

Located above the et apertures 20. are substantially circular deflectors or spreaders 21 provided with clamps 22 which adjustably secure the Spreaders or deflectors to the V lower .arm of the superimposed generator.

The clamp 22, which consists of a split band or ring, is composed of curved resilient sides conforming to-the configuration of the lower arm or portion of the generatorand connected tothe deflector or spreader'by an integral stem. or neck 23 having spaced projecting terminals 24 which" are adjustably connectedby a screw 25. Any other suitable means, such as a plain or continuous'band may be employed foradjustably mounting the SPIGELdGIS or deflectors of the generator. The spreaders or deflectors are adapted to be arranged either horizontally'or at different angles to throw the flame in the desired direction, either to the front of the stove or to the back thereof, or straight upward to facilitate the various cooking operations. The heat from the flames vaporizes the oil in the generator, and the practically perfect combustion, incident to applicants construction, eliminates soot and smoke. Also the oil burner is adapted to do away with much 1 of the noise which is present in many burnarm. The mixing chamber or burner proper 26, the arms or standards 27, and the tubular top portion or generator 28, preferably consist of a casting, and the tubular top portion or generator 28 constitutes a support for spaced adjustable deflectors orsprea'ders 30 constructed similar to those heretofore described, and located above jet openings 31 of the mixing receptacle or burner proper 26. The mixing receptacle or burner proper is constructed similar to the mixing receptacle or burner 1, and is equipped'with an adjustable air and vapor inlet 32located opposite a horizontally disposed discharge nozzle 33 carried by the depending arm 'of the pipe connection 29.

In Figs. 8 to 11 inclusive of the drawings is illustrated another embodiment of the in: vention, in which the mixing chamber or burner proper 34: is provided at its ends with integral upwardly extending arms or stand,

'ards 35 having forked portions 36 at the upper ends to receive the superimposed gen erator 37, whichis adjustably supported in the crotches of the saidforked portions 36 to arrange its discharge nozzle 38 the proper distance from the air and vapor inlet 39'of the mixing receptacle or burner proper. The sides of the forked upper portions 36 of the standards 35 are'curved to conform to the configuration of'the superimposed generator, which has its depending branch or arm 39 operating ina guide40. The guide 10, which is approximately U-shaped, is

composed of spaced sides having outer guiding portions and bent inwardly at the inner terminals thereof to provide adjacent inner portions 41, which are adjustably connected by a bolt 12.- The sides of theguideare connected at their inner portions by an approximately circularbend 43, which embraces the adjacent standard 35. The bolt 42, which is equipped with a thumb nut, is adapted to clamp the horizontal guide to the standard 35 and also to frictionally engage the outer guiding portions of the sides of the guide with the depending arm of the superimposed generator, whereby the latter is retained in its adjustment. The burner is equipped with Spreaders or deflectors 44:, constructed similar to those heretofore described, and .ad-. justably secured to the superimposed generator by their clamps.

While only two jet apertures are shown in the drawings at the top of the mixing chamber, any number, of course, maybe employed, and these maybe arranged in any desired manner, and, in fact, the entire .top of the mixing chamber may be perforated. Also any suitable tubular metal maybe used, such as tubular wire,in the construction of the oil andvapor conduits.

What is claimed is 1. A burner of the class described comprising a mixing chamber having jet apertures at the top, an inlet having a funnelshaped outer portion and provided with a tubular inner portion extending through one wall of the mixing chamber and projecting slightly into the same, a generator located above the mixing chamber and having a depending arm terminating at its lower end opposite the said inlet, means carried by the mixing chamber for supporting the generator in spaced relation with the top of the said mixing chamber, and a horizontal nozzle composed of an exteriorly threaded tubular body having one end screwed into the lower end of the depending arm of the generator, and a cap screwed onto the other end of the tubular body and having a jet aperture, said nozzle being spaced from and discharging into the funnel-shaped outer portion of the inlet, the said inlet and nozzle being both adjustable horizontally toward and from each other.

2. A burner of the class described, including a mixing chamber or burner proper having jet apertures at the top and closed at one end and provided at the other end with an air and vapor inlet, spaced standards extending upwardly from thereceptacle or burner proper and provided at their upper ends with alined forked portions, a superimposed generator adjustably arranged in the forked portions of the standards and having a depending arm provided with a discharge noz? zle located opposite the said air and vapor inlet, and an approximately U-shaped guide v receiving the depending arm of the generator and the adjacent standard and having means connecting the sides of the guide and securing the same to the standard and retaining the generator in its adjustment.

In testimony, that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
